What the vulnerability is
CVE-2024-41710 is an argument injection vulnerability affecting specific Mitel SIP Phone hardware. The flaw stems from insufficient parameter sanitization occurring during the system’s boot process. If successfully exploited, this vulnerability could allow an attacker to execute arbitrary commands within the system context.
Exposure and applicability
This vulnerability applies to organizations utilizing the following Mitel hardware:
* 6800 Series SIP Phones
* 6900 Series SIP Phones
* 6900w Series SIP Phones
* 6970 Conference Unit
Because this flaw occurs during the boot process, it represents a critical point of failure in the device’s initialization sequence. The vulnerability has been added to CISA’s Known Exploited Vulnerabilities (KEV) catalog as of February 12, 2025, indicating that the flaw is not merely theoretical but has been observed in active exploitation.
Remediation priorities
Our analysis suggests prioritizing remediation based on the device’s network placement and its role in the communication infrastructure. The following actions are recommended:
- Inventory Identification: Immediately identify all deployed units within the 6800, 6900, and 6900w series. This is a prerequisite for any mitigation effort.
- Vendor Mitigation Application: Apply the specific mitigations provided in Mitel’s security bulletins. For federal agencies, CISA has established a remediation deadline of March 5, 2025.
- Hardware Decommissioning: In instances where vendor-supplied mitigations are unavailable or cannot be applied to legacy hardware, the affected devices should be discontinued and removed from the network.
How to validate remediation
Verification must go beyond a simple version check, as a firmware update does not inherently guarantee that the specific boot-process sanitization fix was successfully applied and is active.
Defenders should verify remediation by:
* Cross-referencing Build IDs: Confirming that the installed firmware build matches the exact version specified in the vendor’s security advisory for CVE-2024-41710.
* Configuration Audit: Ensuring that any required configuration changes accompanying the patch have been applied across all units, not just a subset of the fleet.
Limits and open questions
While the vulnerability is known to be exploited, it remains unknown whether this flaw has been utilized specifically by ransomware campaigns. Furthermore, because the injection occurs during the boot process, there may be limitations on how traditional runtime monitoring can detect an exploitation attempt in progress. Residual risk remains for any device that cannot be updated or replaced, as these units will continue to be susceptible to arbitrary command execution via argument injection.
